The presence of delamination is a major problem in CFRP laminated panels and so, it is of great concern to both the academic and the aeronautical industrial worlds. Indeed delamination can strongly affect the material strength and, sometimes, can cause their breaking up in service. The aim of this work is to monitor the propagation of delamination during typical applied axial loadings. Therefore, a panel with an embedded delamination was manufactured, and subjected to compression test, while the delamination propagation was being monitored by lockin thermography. The obtained results were used to corroborate the ones coming from numerical computation

Abstract
The presence of delamination is a major problem in CFRP laminated panels and so, it is of great concern to both the academic and the aeronautical industrial worlds. Indeed delamination can strongly affect the material strength and, sometimes, can cause their breaking up in service. The aim of this work is to monitor the propagation of delamination during typical applied axial loadings. Therefore, a panel with an embedded delamination was manufactured, and subjected to compression test, while the delamination propagation was being monitored by lockin thermography. The obtained results were used to corroborate the ones coming from numerical computationI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
